Key indexing practices include:

• Choosing the right data types for indexed columns.
• Regularly analyzing and optimizing indexes for changes in data distribution.
• Avoiding over-indexing, which can lead to increased storage requirements.

Caching can be a game-changer when it comes to reducing fetch time. MySQL provides various caching mechanisms, such as query caching and the InnoDB buffer pool, which can store frequently accessed data in memory for quicker retrieval.
